initializeSelfServiceLoginFlowForBrowsers method

Future<Response<SelfServiceLoginFlow>> initializeSelfServiceLoginFlowForBrowsers({ bool? refresh, String? aal, String? returnTo, CancelToken? cancelToken, Map<String, dynamic>? headers, Map<String, dynamic>? extra, ValidateStatus? validateStatus, ProgressCallback? onSendProgress, ProgressCallback? onReceiveProgress, })

Initialize Login Flow for Browsers This endpoint initializes a browser-based user login flow. This endpoint will set the appropriate cookies and anti-CSRF measures required for browser-based flows. If this endpoint is opened as a link in the browser, it will be redirected to `selfservice.flows.login.ui_url` with the flow ID set as the query parameter `?flow=`. If a valid user session exists already, the browser will be redirected to `urls.default_redirect_url` unless the query parameter `?refresh=true` was set. If this endpoint is called via an AJAX request, the response contains the flow without a redirect. In the case of an error, the `error.id` of the JSON response body can be one of: `session_already_available`: The user is already signed in. `session_aal1_required`: Multi-factor auth (e.g. 2fa) was requested but the user has no session yet. `security_csrf_violation`: Unable to fetch the flow because a CSRF violation occurred. `security_identity_mismatch`: The requested `?return_to` address is not allowed to be used. Adjust this in the configuration! This endpoint is NOT INTENDED for clients that do not have a browser (Chrome, Firefox, ...) as cookies are needed. More information can be found at Ory Kratos User Login and User Registration Documentation.

Parameters:

• refresh - Refresh a login session If set to true, this will refresh an existing login session by asking the user to sign in again. This will reset the authenticated_at time of the session.
• aal - Request a Specific AuthenticationMethod Assurance Level Use this parameter to upgrade an existing session's authenticator assurance level (AAL). This allows you to ask for multi-factor authentication. When an identity sign in using e.g. username+password, the AAL is 1. If you wish to "upgrade" the session's security by asking the user to perform TOTP / WebAuth/ ... you would set this to "aal2".
• returnTo - The URL to return the browser to after the flow was completed.
• cancelToken - A CancelToken that can be used to cancel the operation
• headers - Can be used to add additional headers to the request
• extras - Can be used to add flags to the request
• validateStatus - A ValidateStatus callback that can be used to determine request success based on the HTTP status of the response
• onSendProgress - A ProgressCallback that can be used to get the send progress
• onReceiveProgress - A ProgressCallback that can be used to get the receive progress

Returns a Future containing a Response with a SelfServiceLoginFlow as data Throws DioError if API call or serialization fails
